Explicitly Declare ALL Variables

• Please do not use compiler options to set the floating point precision! (NO f77 –r8 …)

• FOR FORTRAN 77 PROGRAMS:

• Use the NTCC conversion scripts r8_convert and r8_convert_include:

  • See https://w3.pppl.gov/~pshare/help/port_strategy_hlp.html

• First, apply r8_convert to all *.f files.

• Next, apply r8_convert_include to all the Fortran include files used by the *.f.

• Fortran 90 codes ... you have to do it the long way.
